Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

wwbn/avideo versions 29.0 and earlier have several state-changing JSON endpoints that lack CSRF protection. If a logged-in user loads an attacker-controlled page, the attacker can force that user's comment votes, post comments as that user, and delete assets from categories the user manages. No fixed version is listed.
